You are talking about a space elevator and a few years ago a research group
came up with a carbon fiber that actually had the strength required to build
one. Of course with was just in a lab, not production quality material but
they are working on it. And as you build it at the equator you also want the
highest starting elevation you can get. And I hate to be bringing in
economics again but wouldn't it make a lot more sense to make the building
larger and shorter and so you can get the same useable volume with
significantly less material. Or what about going the other way and build
down instead of up?
